[THIN] Re: 4.5 Datastore and Satellites

Strong connectivity, including relatively low latency, is required for zone
data collector/IMA communication. When sites are not linked with good
connectivity they do need to be separate farms. It can be a WAN link, but it
needs to be a decent one.

Syn problems will have IMA service problems. We have the same problem
because of WAN link replication between DS servers....

I work for an organization that ran an Oracle Database and 2 Citrix servers
(4.0) in Brisbane and 4 Citrix servers (4.0) pointing back to Brisbane from
a South Pacific Island over a Satellite link.

 

We had numerous issues with the IMA service starting over the sat link which
caused delays getting the servers back up if there were issues.


We ended up splitting the DS into 2 farms 1 in BNE on the Oracle DB and 1 on
the island on an SQL 2005 DB (There were also other business and technical
reasons for this decision)

 

Needless to say there has been a vast improvement in the IMA service and
server response time and the users are much happier as well.

I have a 4.5 farm using SQL for the DS, and on the other end of a satellite
I have a 4.0 farm that I need to rebuild and bring up to 4.5 as well. I'd
like to collapse them into one farm so I'm pondering what to do about the
datastore; should I setup a SQL server at the remote site and replicate, or
since 4.5 can run indefintely off of the LHC should I just have the remote
server access the DS over the WAN?


The WAN in question is a geo-synchronous satellite, so about 800ms and it's
a pretty heavily utilized small pipe. It's also up and down a lot sometimes.

 

Looking for thoughts, suggestions, experiences, brain farts, etc.

 

thanks.
